aAllows manual adjustment of the output current limit in the 200 - 1200 mA range. bAutomatically limits maximum current output via EEPROM readout. cThe 505 nm LED is not compatible with DC4100.
Thorlabs' collimated LED assemblies can be easily connected to standard and epi-illumination ports on most readily available commercial microscopes, including Leica,Olympus, Nikon, and Zeiss. Each collimated LED consists of a high-power mounted LED and a lamphouse-port-compatible housing that contains an aspheric collimation optic. The collimation of the beam can be adjusted by changing the postition of the aspheric lens with respect to the LED. Interchanging LEDs is easy; simply unscrew one LED from the housing and replace it with a different mounted LED (purchased separately).
Like our MxxxL2 series of mounted LEDs, the LED package of the MxxxL2-C series is in direct contact with the heat sink. Consequently, the degradation of optical output power by increased LED temperature has been minimized. Please see theStability tab for information on the stable output intensity of these collimated LEDs and the LED Drivers tab for information on compatible controllers. If the LED is driven with a DC2100 or DC4100 controller, the integrated EEPROM chip will identify the LED and allow the controller to automatically set the proper current limits in order to protect the LED from being overdriven.
*Due to variations in the manufacturing process and operating parameters like temperature and current, the actual spectral output of any given LED will vary. This plot is only intended to be used as a guideline.
Pin Connection
The diagram to the right shows the male connector of the MxxxLx mounted LED assembly. It is a standard M8x1 sensor circular connector. Pin 1 and 2 are the connection to the LED. Pin 3 and 4 are used for the internal EEPROM in the MxxxLx series. Please note that this pin connection diagram is not valid if you are using an LED driver that was not purchased from Thorlabs.

Optimized Thermal Management
The thermal dissipation performance of the MxxxL2-C series of mounted LEDs has been optimized. The heat sink of the LED package is in direct thermal contact to the heatsink of the LED mount so as to provide best possible thermal dissipation. By doing so, the degradation of optical output power that can be attributed to increased LED junction temperature is minimized (see the graph to the right).

Is the LEDD1 driver the only driver you offer that is plug and play compatible.
